Possible Reasons Why Your Dog Is Snoring

On some occasions, it is usually a bit strange to hear that our pets snore, but it is quite common and harmless. That can also signify that the dogs could have a more severe health problem.

What Is Dog Snoring?

Snoring is caused by vibrations in the soft tissue of the dog’s upper respiratory tract (nose, mouth, or throat) when air passes through them, causing a narrowing that occurs due to swelling, obstruction, congestion, or other problems.

Possible Reasons Why Your Dog Is Snoring

What Causes Snoring in Dogs?

Snoring can occur for a variety of reasons, including:

Upper Respiratory Tract Infection

When the dog shows signs of a cold or respiratory tract infection, nasal congestion can affect a lot, obstructing the respiratory tract and making it difficult for air to flow freely through the nose. These complications will cause the dog to start snoring.

Nasal discharge can also clog the nose, making breathing difficult and producing the sound of snoring. This secretion can be more or less thick, presenting different types of coloration. This can lead the canine to have rhinitis, allergy, or infection.

In these cases, it is good to take the dog to a veterinarian to accurately diagnose the cause of that secretion.


Being overweight in a dog can be a harmful problem in relation to the formation of excess tissue in the neck or throat since the accumulated fat can obstruct air passage during sleep. This increases the chances of snoring in the canine.


When the dog tends to be allergic to certain things, these can be to blame for the snoring generated during the canine’s sleep. Allergies inflame the nasal passages and cause swelling that limits airflow.

Foreign Bodies

Dogs are generally quite curious and want to experience the world through all of their senses, especially smell.

For that reason, many foreign objects accidentally enter their nostrils when they are sniffing plants or spikes, which generate an uncomfortable feeling reflected through snoring while sleeping.

However, that is more likely to cause it to sneeze and runny nose to expel such an object. If it is not expelled, you should urgently take your dog to a vet so he can carefully remove the thing with tweezers.

It is also possible that sometimes a piece of bone gets stuck in its throat and obstructs the passage of air, triggering snoring.

Respiratory Problems

The respiratory system of dogs, like that of people, is quite delicate, so it can be affected by cold and other external factors that cause it to become irritated or inflamed.

Dogs do not escape the possibility of having asthma, tonsillitis, pharyngitis, laryngitis, or other respiratory problems, which significantly influence your pet’s snoring.

Nasal Tumors

This type of pathology usually occurs primarily in older dogs and some breeds, such as the Airedale Terrier, the German Shepherd, and the Basset Hound, which are more likely to have these nasal tumors. These lumps in their nasal cavities make snoring more and more noticeable.

This type of tumor can deform the dog’s face if they are large. They do not have a specific treatment, so many recommend surgery to eliminate them. Keep in mind that if the malignant tumors are usually very advanced, you can only try to prolong the dog’s life through radiotherapy.

Sleeping Position

Some positions can affect the dog’s breathing. When it is lying on its back, this position can cause the tongue to fall back against the throat, blocking the airway.

Abscessed Tooth

Dental disease can commonly cause snoring in dogs, including dental abscesses. 

A dental abscess is the accumulation of pus caused by bacterial infections, which can cause problems in the nearby tissues of the respiratory tract, causing the canine to snore a lot.

Brachycephalic Dog Syndrome

What we have mentioned above can also affect brachycephalic dogs more frequently since this syndrome can be the explanation for the dog’s snoring.

Some breeds of dogs are more affected due to the shape of their broad skulls and short snouts, such as the Pekingese, Pug, Chow Chow, and other dogs of this nature, which are more prone to airway obstruction.

As a result of elongated soft palates that can block airflow in the nostrils and airways while they sleep, snoring will be more frequent.

These harmful formations can alter the dog’s breathing and consequently cause snoring.

Why Does My Dog Snore So Loud?

In the following table, you can see the reasons why dogs snore more than usual:

CongestionExcess mucus in the airways
Heavy BreathingDogs may have heavy breathing to regulate their temperature, and this is usually due to a more severe health problem.
Sleep apneaDisorder that affects the dog’s breathing while it sleeps

What Can I Do to Reduce Snoring?

Now that you know why a dog snores, preventing or reducing snoring can often be as simple as helping your pet lose a little weight. If your dog is overweight or obese, your veterinarian can help you create a weight loss meal plan that will allow your pet to more safely lose those pounds.

If the cause is a cold or an upper respiratory infection, the snoring will likely stop on its own after some time. However, treatment is always recommended to reduce these discomforts.

These are some measures that we can adopt if our dog shows respiratory difficulties:

  • Clean its nostrils daily
  • Use a harness instead of a collar
  • Avoid exposing the dog to high temperatures since the cold could cause a cold
  • Walk it through areas with shade
  • Always carry a bottle of water to refresh the dog when you walk it
  • Control food and water to prevent choking. We can do this by offering small pieces of food
  • Avoid obesity
  • Do not encourage moments of stress or allow intense exercise.
